To all whom it may concern. 7

Be it known that I, EMIL Gr. J URe'ENs, a Citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have inventedcertain new and'useful Improvements in Package-Identification Apparatus, of which the following is aspecification. V 1

My invention relates to improvements in package identification apparatus, and al thong-11 of Wide application is of partlcular service in connection with theidentification of such packages; as cartons; in which are packed manufactured products Siib ect to considerable vai iati'on in quality.

I The principal objects of iny invention are to provide mechanism for idehtification purposes Whichmay' be applied conveniently to 7 existing types of inachines'us'ed for packag- 'ing, which includes machines for forming the packages, for instance, cartons; to pro vide a chnstriiction in which the indici'a plied to the package may be changed from time to time with convenience and dispatch;

to provide a construction such that there will be substantially no interference With the operation of thepackaging', including carton-forming mechanism; to provide a construction which inay be quickly and conveniently adjusted, both as to its own operation and to conform with the operation of the main package-forming rnechanisni; to provide a construction which shall be simple and economical to design and manufac titre, While being inexpensive and conven- 1 ient to maintain and operate, and in general to provide'an improved identification apparatus of the cliai'actei reierredto.

As illustrative of a preferred :en'lbodiinent of my invention, I have shown the same as L'Ipplied to a machine of the type shown'in' t e United States patent to F raiik Peters, No. 1,025,880; patented May'T, 1912.

In the'draivings illustrating said application:

Fig. 1 is a side elevation of the identi- V fication apparatus and parts of the main Peters inachine, associated therewith,

Fig. 2 is a sectional plan view taken on the continuously inovi'ng conveyor chain of the patented carton-forimnpg machine, said chainzpassingover an oi 'erhead constantly actuated horizontal shaft-11, said sl'ia'ft b'e ing fitted with the usual sprocket Wheel 12 around which said chain is trained. It Will not be necessary for me to describe the operation of the forming heads 13 carried by said chain 10, as the fuhctidn of said heads is adequately described in the said Peters patent; It will be'sulhcient to say that the machine receives suitably scored blanks 14,

which upon descent of the heads 13, and in conjunction With other; forihing' insti'umentalities not shoivn, are formed up into open top cartons ready to receive bakery or other prodiict.

The blanks 14am fed into theihachine horizontally in the directioiil of the arrow 15, the feeding" n oveii entheih; arrested by suitable stop members l6zand 17., Preferblock 23. Said type block '23'is flanged or headed-at its upper end as indicated at 24, in orderthat it inay be securely and rigidly supported in the apertured extension 225 and l in order to pre've'ntit from moving due' to vibration or other causes, I preffel to eihploy small lock ball 25;" The hall 25 is arranged to co-operate with a sni'all recess formed as shown in theside of th'eQtype block 23 and ispressed into said meat means of a small coil compression spri1ig26 seated in a horizontally extending opening bored in a small boss 27 on theend of said extension 22. A small screwy pl'u 28 threaded into the end of said bore durnishes a b'ackingfor the end of spring 216. 4

The type block 23 isinade with vertically extending rectang'ularfop'ening or? Chink ,nel therethroug h, the hottdnilef which is closed a stop; plate 29 ri idly" secured; to .1 the lower end (if the'type. b och; "Said rec tangular vertically extending opening accommodates aset of suitable steel type members 30 which cooperate with a hammer member 31, presently to bedescribed more in detail. The end of the extension 22 and type block 23 constitute an anvil for the hammer 31, which on its descent impresses upon the under-side of the cartoneblank 14, markings corresponding with the type 30. In the present instance, the type block is shown as being equippedgwith three typefor marking the flap of a carton with the numerals 182., Said numerals182 represent any desired identification data, forinstance, the day or 'the year, a special batch or the product of aparticular oven. The arrangement is such that the type may be quickly and conveniently changed whenever/it is desired tochange the data to be applied to the carton. I e

The hammer 31 is actuated as an incident to the operation of the main carton-forming mechanism and by the following mechanism. It will be observedthat the bracket 20 is formed with an integral upwardly projecting lug 32, said lug being tapped to receive the threaded end of a stationary pivot pin 33. Said pivot pin 33 is locked securely in position by'a nut 34 applied to the end, of the threaded portion of pin 33. The stationary pin 33 constitutes a fixed pivot for a rocking member, which is made with a pair of angularly disposed arms, the arm 34 serving as a holderfor the hammer 31, while the arm 35 controls the movement of the rocker. Said hammer 31 is mounted .on the end of arm 34 by providing said ham mer with a stem 36 extending through the end of arm 34 and secured therein by a back-nut 37. I

7 Energy for actuating hammer 31 is supplied by a coil spring 38 which tendsto pull said arm 34 downwardly at all times. One end ofsaid spring 38 is hooked into an aperture in extension 22, While the upper end of said spring 38 is hooked into an aperture 39 formed in the end of a tension regulating screw 40 threaded into an enlargement 41 of arm 34 andrigidly locked in position by a nut 42.

' The operation of the arm 34 under the influe-nee of spring 38 is controlled by a cam I 43 keyed to the shaft 11 and madefn the form of a disk having cam notches 4-4 ormed therein. Said cam notohes44 co-operate with a small cam roller 45 mounted on a pin 46 in the end of the upper arm .47 of abell crank,said bell crank being oscillatably mounted on'a fixedpivotpin 48. The lower arm 49 of said bell crank is of considerably greater length than'the upper arm 47 ,in order to multiply theamount of movement of the lower end of said arm 49. Said lower end is formed with a fork 50 which straddles a roller 51 rotatably carried by a pin 52 seated in the upper end of the control arm 35 of the rocker.

In view of the above description, the operation of the hammer member 31 will be readily understood. Normally the concentrio surface 52 of cam 43 maintains the parts in the position shown in Fig. 1 with the hammer 31 lifted out of operative position and against the action of spring 38. As soon however, as the movement of the shaft 11 brings the notch 44 into register with cam roller 45, the lattercan drop into said notch and permit spring 38 to snapthe hammer 31 down upon the anvil, thereby causing the type 30 to make anvimpression upon the under side of carton blank '14. As soon as the hammer has performed its marking function, the cam roller 45 rides up on thesloping portion, 53 of notch44 and causes the parts again to assume the position shown in Fig. 1. It will be manifest that the cam 43 isso timed with reference to the cartonforming instrume-ntalities that when the hammer 31strikes the anvil, carton blank 14 will be in position to receive the blow.

The above details of construction and operation being merely. .illustrative of-a single application of my invention, it will be understoodthat the scope of same should .be determined by reference to the appended mer member co-acting with the operative face of said anvil to operate upon a P01111011 of the carton, said anvil member being equipped with changeable indicia, and means for actuating'said hammer.

. 2. A carton-forming machine provided with means for forming a carton from a single blank, an anvil member having marking devices on one face thereof and a hammer member co-acting with the operativev face of said anvil to operate upon a portion of the carton, said anvil member being equipped with changeable. indicia, and means for vactuating said hammerias an incident to the operation of the forming mechanism.

3. In a machine of the class described, the combination with means for forming a car ton, of an impression member equipped with changeable indicia, and a spring-actuated hammer member co-acting with the operative face of said die member to mark said carton as an incident to the operation of said forming means. ii

I 4; In a machine of the class described, the combination 'withmeansfor forming a carton, of a type block forming an anvil and equipped with changeable indicia, ahammer member co-operating with said block, and means for actuating said hammer to cause the sameto deliver a sharp blow upon said block to mark said carton as an incident to the operation of said forming means.

5. In a machine of the class described, the

combination with means for forming a carton, of a die block forming an anvil and equipped with changeable indicia, and a cam-controlled spring-actuated hammer cooperating with said blockto mark said carton as an incident to the operation of said forming means. r

6. In a machine of the class described, the combination with mechanism for forming a carton, including means for advancing the blank, of means for applying suitable indicia to the said blank during said advance, com- )i'isin a twe block forming an anvil a hammer disposed opposite to the operative face of said anvil and adapted to deliver a sharp blowthereto as the blank passes there-- between, and, means actuated by said carton forming-mechanism for actuating said hamrelative thereto, changeable indicia in said anvil, a cam controlling the movement of said hammer, and a spring tor causing said hammer to d'ehvera sharp blow upon said anvil.
